I've only owned this boat 2 years and have used 10w40 Suzuki Motorcycle oil. I was told it was the same as Outboard oil and that is all they can get. I'm in Hanover, On Canada and it seems like my options are limited. Do I need to stick to Suzuki oil or what would someone recommend. This is conventional oil not synthetic. I usually just troll with it.

It is funny because the lures I have don't have any paint on them but they still catch fish just not as good as they were when they had paint on them This lead me to believe it was the action but I found a bunch of the same lures only a different colour and they just don't produce.
